The Solar Orbiter has been zipping through these gravity assists since last year; it’s scheduled to make a total of six, five of which are Venus flybys.
BepiColombo made one Earth flyby in April 2020 and a Venus flyby last October, and is scheduled to make six flybys of Mercury by 2025.
BepiColombo will see Mercury for the first time in early October, and the Solar Orbiter will make its final pass by Earth in late November.The data from the upcoming Venus flybys could eventually be of use to the ESA’s EnVision orbiter, set to launch for Venus in the early 2030s.
